All the things you mention here certainly bring together the puzzle, THANK 
YOU!!!

My GP is #222141

The tool boxes I have seen all have a 1/8" diameter hole located on the lid 
centered on the non-hing edge.  Definately not a home made hole as all are 
the same.

The replacement air cleaner explains why the radiator does not have the bolt 
hole.

I will need to run out and look at the parts tractor and see if there is 
anything remotely looking like a pto attachment.

This is all great information.
